Blender Video & Audio out of horribly sync and missing my cuts
There were small errors, 4 in total, in the video. Places where the video and audio would freeze for ~10-15 seconds which threw off Blender's A/V syncing.

While editing the errors out in Blender I discovered that allowing it to slowly advance while rewinding and listening helped in isolating the bad spots. The audio/video would always resume playing from the same place, despite the advancing rewind point, until I reached the end of the corruption then play would advance normally.

I hope my explanation was clear. Be sure to check your videos for corrupt sections before editing. Good luck!
